 ## Debugging
+
 - Create a pull request, ideally with commits that update dependencies
-- Download the `github-context` artifact from Github Actions run for the PR. That artifact should have the JSON file with the context of the Github event.
-- Put the `event.json` file into the root of this repository
+- Once the test run is finished, rerun it with debuggin enabled
+- Take the JSON context from debug logs (after `ReportUpdatedDependencies context that can be used for testing:`) and save it as test-context.json into the root of this repository
 - Add the following code to `.env` file
   ```
-  GITHUB_EVENT_NAME=pull_request
-  GITHUB_EVENT_PATH=event.json
   INPUT_TOKEN=<YOUR_GITHUB_TOKEN>
   ```
-- Hit F5 in VSCode to start debugging
